The Witcher season 1 was mainly concerned with the original stories of Geralt, Yennefer, and Ciri - and how the three characters end up crossing paths - but it also included some major clues about what's to come in season 2 and beyond. Based on the books by Andrzej Sapkowski and adapted for TV by showrunner Lauren Hissrich, The Witcher stars Henry Cavill as monster-hunter Geralt of Rivia, Anya Chalotra as powerful sorceress Yennefer of Vengerberg, and Freya Allan as the young princess Ciri.

Geralt and Ciri's futures have been bound to one another ever since the princess was unwittingly gifted to him as a "child of surprise." Geralt, who cannot have children of his own due to the mutations he underwent in his witcher training, wasn't particularly interested in having a daughter. Nonetheless, he eventually returned to Cintra to claim Ciri and was united with her in The Witcher's season 1 finale. Along the way there were plenty of hints that Ciri has some kind of grand destiny - and the documentary Making The Witcher reveals one particularly big clue that was hidden in plain sight.

As spotted and translated from Hen Linge (Elder Speech) by Reddit poster BWPhoenix, the engraving on the magnalith that Istredd discovers reads, "And to orphans, earth's destiny belongs, for they are the keepers of the lion's scion." The reference to "orphans" is about Yennefer and Geralt, both of whom were given up by their parents rather than technically being orphaned (though by the end of the series Yennefer's parents will be dead anyway due to how much time has passed, and Geralt's father is dead as well). "Keepers of the lion's scion" refers to the two of them being Ciri's guardians, since Ciri is also known as "the lion cub of Cintra." In summary, the magnalith's prophecy is foreshadowing that the destiny of the Continent lies with Ciri - and, by extension, the people who will watch over her.

The Witcher Magnalith

This particular magnalith appears in episode 7, "Before A Fall," when Yennefer visits Istredd at an archeological dig site in Nazair, a land recently conquered by Nilfgaard. Istredd explains that there had been rumors of a magnalith, but no one had been able to find it until he arrived. He tells Yennefer, "Every glyph has a clue to something across the Continent from a time before the Conjunction [of the Spheres]."

This cataclysmic event took place 1,500 years before the start of The Witcher's story, and brought other worlds crashing together and merging on the Continent. The land had previously been occupied only by the Elder Races - including elves, gnomes and dwarves - but after the Conjunction the world was filled with both humans and monsters as well. The humans, by virtue of being the most ruthless and ambitious new species, ended up conquering the Continent and turning the Elder Races into hunted fugitives and second-class citizens.

Regarding the inclusion of the magnalith in The Witcher season 1, production designer Andrew Laws explains in Making the Witcher that "We're peeling away layers of the onion. We're beginning to do that in season 1, and there are a lot more layers that come. So we wanted to... tease a little bit what might be revealed as we get further into the story." The magnaliths are remnants of the civilizations that existed before the Conjunction of the Spheres, and they contain prophecies regarding what to expect in the future. Readers of the Witcher books will already know exactly why Ciri is so special and what her future holds, but for those who are only familiar with the TV show, the magnalith is a tantalizing clue as to what to expect in The Witcher season 2 and beyond.
